Thermal waves or beam heating in the 1980, November 5 flare
Observations of the temporal evolution of loop BC in soft X rays in the November 5, 1980 flare are reviewed. Calculations are performed to model this evolution. The most consistent interpretation involving a minimum account of energy is the following. Thermal heating near B gives rise to a conduction front which moves out along the loop uninhibited for about 27 s. Beam heating near C gives rise to a second conduction front which moves in the opposite direction and prevents any energy reaching C by thermal conduction from B. Thus both thermal waves and beam heating are required to explain the observed evolution
After, Before and During: Returns to Education in the Hungarian Transition
How valuable are the education and skills acquired under socialism in a market economy? This paper uses data for about 3 million Hungarian wage earners, from 1986 to 1998, to throw light on this question. We find that returns to schooling reach 10 percent early on and remain at this high level. These estimates are larger than for other transition economies, but similar to those for middle-income developing countries. With the gap in average years of schooling unremitting, we argue that the Hungarian stock of human capital is considerably less than the existing figures have led us to believe.http://deepblue.lib.umich.edu/bitstream/2027.42/39860/3/wp475.pd
